There is no information about LANKAR requirements on its official website. I recently installed this application on my computer and I can tell you that it works right. I have a dual-core Pentium (3.00GHZ) with 4 GB RAM with WIndows 7 (64-bit). Moreover, if you have a lower performance computer, I recommend that you get in touch with the developer at: [email protected] and ask him the minimum requirements for this application. If you want to download this application you can choose between two versions PRO and Enterprise. The Pro version cost is: 159.00 dollars/m and the Enterprise version cost: 189.00 dollars/m.
